Procedure
A solution of [6-(4-cyanophenyl)-5-(2-furoyl)-4-methyl-2-oxo-3-[3-(trifluoromethyl)phenyl]-3,6-dihydropyrimidin-1(2H)-yl]acetic acid (Example 29A) (75 mg, 0.15 mmol), 2,2,2-trifluoroethane-sulfonamide (23 mg, 0.16 mmol), 1,3-dicyclohexylcarbodiimide (33 mg, 0.16 mmol) and 4-dimethylaminopyridine (20 mg, 0.16 mmol) in dichloromethane (4 ml) is stirred at room temperature for 4 days. The product is extracted with dichloromethane (100 ml), washed with 2 N hydrochloric acid and brine, dried over magnesium sulfate, filtered and concentrated in vacuo. The residue is purified by preparative HPLC (RP18 column; eluent: acetonitrile/0.1% aq. formic acid 30:70→90:10). The title compound is isolated as a colourless solid.
